Cartridge or Pre Amp


I recently picked up the Pro-Ject Tube Box DS and I am tickled pink on how warm and yet dynamic it remains. I’ve noticed that there seems to be some front stage darkness on some older records. Nothing more volume can’t fix. Would upgrading my AT-ML150 cartridge or the pre amp would this phenomenon or it simply a characteristic of the production and pressing of its day?


My setup:

Technics MK1200 MKII various upgradeds: wires, tonearm, etc.
AT-AL150/OCC Cartidge
Pro-Ject Tube Box DS
Bryston 4B3
Bryston Model T speakers
Simaudio MOON NEO Preamp
OPPO UDP-205

Thanks @chakster for the valuable information you provided. I'm all in for testing various components and hearing the results. Of course results may vary. I'd like to start out by testing the ATN170 / ATN180 styli, a high output MC.Testing various various tubes and finally different sound stages. Thanks for posting the links. This has been very educational even to a audiophile like myself.
@invictus005 Unfortunately I need a subsonic filter due to my systems dynamic nature...alas the Parasound JC3 lacks one.

A subsonic filter is a band aid patch to try and correct something that is wrong with a Music Reproduction System but such filters suffer inherent problems and the course of best resort is always to identify, isolate and correct the problem at the source rather than try to conceal it utilizing additional electronics that are not necessary or preferred.
It is possible that those records which do not sound as dynamic are not as good as the recordings which do; it may not be your equipment.
@jimf42 I totally agree. The sensitivity of my setup is such that media production is crucial. As with any high end systems, poor recordings will be amplified.
